Test Bench: Two Beryllium Tweeters from Scan-Speak - …

I began testing the new Scan-Speak beryllium tweeters, the D3004/604000 and the D3004/604010, by generating a stepped sine wave impedance plot using the LinearX LMS analyzer. Figure 1 shows the results of the LMS 300-point impedance sine wave sweep for both tweeters.

The h-15 is fitted with a 2-channel power amplifier module that supplies 830W long-term, sine wave (2000W peak) to the LF transducer, and 275W long-term, sine wave (400W peak) to the beryllium compression driver.

Test Bench: Scan-Speak D2908/714000 Revelator Beryllium …

I used the LinearX LMS analyzer to begin testing the D2908 beryllium dome by generating a stepped sine wave impedance plot. The result of the LMS 300-point impedance sine wave sweep is shown in Figure 1. The tweeter resonance is 525 Hz. Minimum impedance for this tweeter is 6.1 Ω at 4.8 kHz with a measured RE equal to 5.69 Ω.

Focal Utopia Headphones | The Absolute Sound

From its lowest register to its highest frequencies the Utopia speaks with an authoritative voice. With no crossover to affect phase its sound is coherent and articulate. The drivers are matched so well that when I ran my standard full-range sine-wave sweep in mono (15Hz to …

Optical Interference Filters - Materion

A single sine wave structure has strong side lobes. In order to suppress the side lobes, the sine function above is apodized. It is also impedance-matched to the incident media and the substrate which produces a single notch. The resulting index profile is shown in Figure 1.

MEASUREMENTS OF THE PROPERTIES OF BERYLLIUM FOIL

Beryllium is the structural metal with the lowest atomic number, so that it is the best candidate for a window to minimize scattering of the muon beam. Therefore, beryllium operated in liquid nitrogen temperature is very interesting. However, the data on handbook are for high17 pure beryllium.

I began the driver characterization process by using the LinearX LMS analyzer to produce the 300-point sine wave impedance plot shown in Figure 1. The solid black curve represents the beryllium diaphragm 745NEOBe mounted on the ME90 horn and the dashed blue curve represents the beryllium compression driver without the horn.

A Coupled-Reactor-Commutating Sinusoidal-Wave Inverter

A coupled-reactor-commutating sinusoidal-wave current-source inverter is described. The inverter consists of two coupled-reactor-commutating inverters. By superposing the output currents of these two inverters, output currents of a 180?? conducting angle are formed, and are controlled in order to achieve a sinusoidal waveform.
